Circul Sleep & Fitness Ring

CIRCUL is a pulse oximeter ring that can be worn comfortably day and night as a continuous blood oxygen and heart rate monitor. Contrast this with a traditional bulky finger clip oximeter that covers most of your finger tip or may have a cord attached, and cannot be worn comfortably. A common finger clip oximeter does not allow for continuous blood oxygen monitoring. Additionally, studies show that a pulse oximeter that clips to your finger tip may be less accurate in dark pigmented skin; people with poor circulation or especially due to nail polish covering your nail bed. As a health ring, you are able to monitor oxygen saturation and heart rate throughout normal daily activities, including sleep, workouts, regular daytime activities, and working.
